Nuvaring **PLEASE HELP**

Madison

I just started Nuvaring December 17th, my first time on it, I took it out on the 7th of this month, the three week mark. My period still hasn’t shown up, I’m having cramps, and I’ve been grouchy, migraines. Is this a common thing? To miss your first period with the Nuvaring? I seem to be having the symptoms but no bleeding.
